More Information
Summary:The invention discloses a preparation method of microwave ferrite, and belongs to the technical field of ferrites. The preparation method comprises the steps of (A) molding powder to obtain a green body; (B) sintering the green body to obtain a half-clinkered blank; (C) processing the half-clinkered blank to obtain a semi-finished product; and (D) sintering the semi-finished product to obtain a ferrite matrix finished product. According to the invention, through step-by-step sintering and grinding processing of the half-clinkered blank between two steps of sintering, the problem that a substrate with a special structure required by a novel microwave ferrite device is difficult to produce and process is solved. Compared with an existing one-step sintering method, the method has the advantages that direct and complex processing of a polycrystalline clinkered blank with high hardness and brittleness is avoided, large-scale production capacity is achieved, the yield is increased by reducing processing stress dama
